Problems solved by technology

[0004] However, for 4G and 5G interoperability between different systems, if the traditional connection interoperability mechanism is used, the terminal will measure all 5G neighboring cells, and when the measurement reporting conditions are met, the terminal may switch to the 5G neighboring cell. After switching to a 5G cell, the terminal works abnormally because the terminal cannot process the 5G signaling issued by the 5G cell

Abstract

The invention discloses a connection management method, a first network device, a terminal device and a system. The method includes: obtaining capability information of at least one adjacent cell; obtaining capability information of a terminal device in a serving cell managed by itself; Selecting at least one neighboring cell to be measured for the terminal device based on the capability information of the terminal device and the capability information of the at least one neighboring cell; based on the at least one neighboring cell to be measured reported by the terminal device A measurement report, determining to handover the terminal device to a target cell in the at least one adjacent cell to be measured, or determining to configure dual connectivity for the terminal device; wherein the dual connectivity indicates that the terminal device is connected to the Establish a connection with the serving cell and the target cell.

Description

technical field [0001] The present invention relates to information acquisition technology in the communication field, and in particular, to a connection management method, a first network device, a terminal device and a system. Background technique [0002] 5G can be seen as a re-evolution after LTE, that is, the evolution also introduces innovative new technologies. Currently, 3GPP defines two schemes for 5G New Radio (NR) networking, namely, Standalone (SA) and Non-Standalone (NSA). Among them, non-independent networking refers to the independent deployment of 4G control plane (4G bears control signaling), the joint deployment of 5G and 4G user plane (5G and 4G bear user plane data) or the independent deployment of 5G user plane (only 5G bears the user plane) Data); independent networking refers to the independent deployment of 5G control plane and user plane (5G independently carries control signaling and user plane data), and the independent networking mode of 5G new a...
